The situation is the following:
Starting with kernel 2.6.15 i started to have a strange problem with the sound of my Tvcard. It is recognized and all by i get only a loud noise instead of sound...Image is normal.
After i messed around a bit i found that i could get the sound working by removing the modules and modprobing them again, but its kinda of boring to do it everytime i boot and want to start xawtv...
Anyone have a clue on how to solve this?
Here is some output:
Code:

To solve this (stop the noise and start to have normal sound output from the TVCARD) i do:
Code:
rmmod bt878
rmmod bttv
modprobe bttv
Thanks!
